The ADT7408 is the first digital temperature sensor that complies with JEDEC standard JC-42.4 for Mobile Platform Memory Module. The ADT7408 contains a band gap temperature sensor and 12-bit ADC to monitor and digitize the temperature to a resolution of 0.0625°C. There is an open-drain Event# output that is active when the monitoring temperature exceeds a critical programmable limit or the temperature falls above or below an alarm window. This pin can operate in either comparator or interrupt mode. There are three slave-device address pins that allows up to eight ADT7408s to be used in a system that monitors temperature of various components and subsystems. The ADT7408 is specified for operation at supply voltages from 3.0 V to 3.6 V. Operating at 3.3 V, the average supply current is less than typically 240μA. The ADT7408 offers a shutdown mode that powers down the device and gives a shutdown current of typically 3 μA. The ADT7408 is rated for operation over the –20°C to +125°C temperature range. The ADT7408 is available in lead-free 8-lead LFCSP 3mm x 3mm (JEDEC MO- 229 VEED-4) package.
